Update TheAlteningAccount.java

[1532658585]

Type of change

• [X ] Bug fix
• New feature

Description

Fixes an issue where TheAltening accounts could log in in the alt manager but failed to join servers with:

MinecraftClientException: Failed to read value {}

The problem was that TheAlteningAccount.login() was switching the whole ApiServices environment over to TheAltening’s hosts. That made Mojang’s authlib call endpoints that don’t fully match what it expects, so some responses came back as {} and blew up. This behavior was likely introduced in the chat security updated or on some variant of the 1.20.X versions

The new login():

• Uses WaybackAuthLib to log into TheAltening and get the profile + token.
• Calls super.login() so the client keeps using the normal Mojang environment.
• Applies the TheAltening session with setSession(new Session(...)).

Alt manager behaviour stays the same, but TheAltening accounts can now actually join servers.
